How does the Polar Dust affect the Correlation between Dust Covering Factor and Eddington Ratio in Type 1 Quasars Selected from the Sloan Digital Sky Survey Data Release 16?

Posted by klaurent Peking

Kavli Affiliate: Claudio Ricci | First 5 Authors: Yoshiki Toba, Yoshihiro Ueda, Poshak Gandhi, Claudio Ricci, Denis Burgarella | Summary: We revisit the dependence of covering factor (CF) of dust torus on physical properties of active galactic nuclei (AGNs) by taking into account an AGN polar dust emission. The CF is converted from a ratio […]

Breaking the degeneracy between polarization efficiency and cosmological parameters in CMB experiments

Posted by klaurent Stanford

Kavli Affiliate: W. L. Kimmy Wu | First 5 Authors: Silvia Galli, W. L. Kimmy Wu, Karim Benabed, François Bouchet, Thomas M. Crawford | Summary: Accurate cosmological parameter estimates using polarization data of the cosmic microwave background (CMB) put stringent requirements on map calibration, as highlighted in the recent results from the Planck satellite. In […]

Adiabatic waveforms for extreme mass-ratio inspirals via multivoice decomposition in time and frequency

Posted by klaurent MIT

Kavli Affiliate: Scott A. Hughes | First 5 Authors: Scott A. Hughes, Niels Warburton, Gaurav Khanna, Alvin J. K. Chua, Michael L. Katz | Summary: We compute adiabatic waveforms for extreme mass-ratio inspirals (EMRIs) by "stitching" together a long inspiral waveform from a sequence of waveform snapshots, each of which corresponds to a particular geodesic […]

Two Massive Jupiters in Eccentric Orbits from the TESS Full Frame Images

Posted by klaurent MIT

Kavli Affiliate: Roland K. Vanderspek | First 5 Authors: Mma Ikwut-Ukwa, Joseph E. Rodriguez, Samuel N. Quinn, George Zhou, Andrew Vanderburg | Summary: We report the discovery of two short-period massive giant planets from NASA’s Transiting Exoplanet Survey Satellite (TESS). Both systems, TOI-558 (TIC 207110080) and TOI-559 (TIC 209459275), were identified from the 30-minute cadence […]

Improved Spatial Resolution Achieved by Chromatic Intensity Interferometry

Posted by klaurent MIT

Kavli Affiliate: Frank Wilczek | First 5 Authors: Lu-Chuan Liu, Luo-Yuan Qu, Cheng Wu, Jordan Cotler, Fei Ma | Summary: Interferometers are widely used in imaging technologies to achieve enhanced spatial resolution, but require that the incoming photons be indistinguishable. In previous work, we built and analyzed color erasure detectors which expand the scope of […]
